Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 510,576,391, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
1 | 510,576,391 | |
-1 | -510,576,391 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 510,576,391.
Example:
1 x 510,576,391 = 510,576,391
and
-1 x -510,576,391 = 510,576,391
Notice both answers equal 510,576,391
With that explanation out of the way, let's continue. Next, we take the number 510,576,391 and divide it by 2:
510,576,391 ÷ 2 = 255,288,195.5
If the quotient is a whole number, then 2 and 255,288,195.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
1 | 510,576,391 | |
-1 | -510,576,391 |
Now, we try dividing 510,576,391 by 3:
510,576,391 ÷ 3 = 170,192,130.3333
If the quotient is a whole number, then 3 and 170,192,130.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
1 | 510,576,391 | |
-1 | -510,576,391 |
Let's try dividing by 4:
510,576,391 ÷ 4 = 127,644,097.75
If the quotient is a whole number, then 4 and 127,644,097.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
1 | 510,576,391 | |
-1 | 510,576,391 |
If you did it right, you will end up with this table:
1 | 13 | 39,275,107 | 510,576,391 |
-1 | -13 | -39,275,107 | -510,576,391 |
